The potential difference across the ends of a conductor is $(50 \pm 3) \text{ V}$ and the current through it is $(5 \pm 0.1) \text{ A}$. The percentage error in the measurement of resistance of the conductor is (in $\%$)

The formula for the physical quantity is $P = \frac{x^3 y}{z^2}$ and the percentage error in the determination of physical quantities $x, y, z$ are $0.6 \%$,$3 \%$,and $1.3 \%$ respectively. The percentage error in the measurement of $P$ is (in $\%$)

An experiment is performed to obtain the value of acceleration due to gravity $g$ by using a simple pendulum of length $L$. In this experiment,the time for $100$ oscillations is measured by using a watch of $1$ second least count,and the value is $90.0$ seconds. The length $L$ is measured by using a meter scale of least count $1$ mm,and the value is $20.0$ cm. The error in the determination of $g$ would be ........... $\%$.

The amount of heat produced in an electric circuit depends upon the current $(I),$ resistance $(R)$ and time $(t).$ If the error made in the measurements of the above quantities are $2\%, 1\%$ and $1\%$ respectively then the maximum possible error in the total heat produced will be ........... $\%$

Write the rule for the error produced in the result due to the addition and subtraction of physical quantities.

The radius of a sphere is $(5.3 \pm 0.1) \, cm$. The percentage error in its volume is
